If you want something more comparable, how about this: as far as we can tell, pretty much the entirety of Africa completely failed to manage Covid-19. Infection rates there as measured by antibody testing were massive, the population was more than than enough to produce mutations, and it has already resulted in a mutation that's been confirmed to evade at least one crucial vaccine. Yet we haven't seen this kind of narrative about Africa.
If you say so. Here Brazil has always been of particular interest due to our close historical relationship, so nothing has changed (e.g. "Lava Jato" was also covered much more closely than corruption cases in other countries, left or right-wing).
My guess is they’re saying if you have a population of 20, you have 20 chances of mutation. If you have a population of 200M, you have 200M chances of mutation. Size matters.
Following that logic China and India should be a lot more problematic than Brazil. As a matter of fact, both of those countries "mismanage" Covid-19 as well.
Yes, and for a fixed mutation chance, the bigger the population, the greater the likelihood that a mutation will happen. Say a mutation has a 1 in 1000 chance of happening. For a disease that infects 1000 people, you would expect 1 person to end up with some mutation. If the same disease infects 1,000,000 people, you would expect 1000 mutations to occur.
